What occurs if the ADU mode selector is set to AUTO?

When the ADU (Automatic Deployment Unit) mode selector is set to AUTO, the SSK (Stability Control System) is programmed to deploy automatically under specific conditions. In this case, it means that the SSK will deploy 4.0 seconds after seat-pilot separation. This timing is crucial for ensuring the pilot's safety, allowing for an appropriate interval to prevent deployment under potentially dangerous circumstances.

The AUTO setting is designed to function when the systems detect an ejection, coordinating the deployment at just the right moment. This designed delay helps to ensure that the parachute can deploy safely without interference, contributing to the safety systems of the aircraft. Understanding this operation is essential for pilots and crew, as it affects emergency procedures during critical flight situations.
